Sorry, one more question, is that the entirety of the video evidence? Or did you stop it prematurely?
You stopped quite early in the box so it might be possible to construct an argument that you actually could have continued moving forward at a slow walking pace, not reaching the other end before the get car starts moving again a few seconds later. Very much a long shot I think, and if the video continues longer than what you've uploaded with the grey car stationary then there's no point even trying that one.
